Conclusion: “Acoustic rhinometry has a definite advantage [to rhinomanometry] because it is not dependent on airflow in the nose, and it is therefore suitable for severely congested individuals. It also appears to be more sensitive to changes in obstruction, probably because the measurement of cross-sectional area represents the location of minimal airflow, which determines the degree of obstruction experienced by the individual.”

“In conclusion, acoustic rhinometry correlates well with and is superior to Rhinomanometry in assessing the response to nasal allergen challenge, especially in patients with an initial degree of nasal obstruction.”
